Here's a restoration of one of The Second Arrangement. Original versions of this are plagued by bleed in, bad cassette audio, and a lot of other problems.
So I decided to restore it, it's not perfect by any means, but it's by far better sounding than any other rips online of this specific version. Lossless versions of the restored demos can be downloaded on the Internet Archive here: https://archive.org/details/LostGauchoRestored
Change made for the restoration (all done with Izotope RX7): Fixed L and R channel tape sync and volume issue, EQ matched with MFSL CD, boosted vocals and lowered bass significantly using a neural network, de-clipped, manual EQ, over 200 manual declicks and attenuates for high end bleedthrough.
